amazing red here - You can use GIMP to select a colour (select tool) then recolour it a different colour (paint fill), and gradually do that for the full object shading to match - not that I've done it since my first 365, so would have to teach myself again. I guess there's a similar route in Photoshop - video here for one route https://www.youtube.com/watch?v=n9fwiNyDHLI
@shannejw Thanks so much Shanne, I have uninstalled Gimp as it is too much to start learning for me. A already have more than I can chew, lightroom, topaz studio, photoshop elements and photoshop. I am concentrating on PS now and your link will come in useful :-)
